Sprint appears to be redoing the B41 Coverage map on a city by city basis. Much more realistic than prior version. Slight exaggeration remains in a few local spots, but this is far far outweighed by B41 that is not shown. http://coverage.sprint.com/IMPACT.jsp?INTNAV=SJS:HE:Cov

So in my discoveries of latching onto B41 I have noticed several oddities.
Mainly speed; and those horrible pings!: image
Is this tower somehow still connected to old WiMax backhaul? (regardless of which tower I am connected to speeds are in the pits like shown above). image

I am supposed to be in a Sprint Spark Turbo market and the speeds are considerably worse than B25, B26 seems to be in testing I don't stay connected long enough to do any tests. But regardless of signal strength the speeds are generally the same on B41. Don't know if this is in the right place but I figured I would take a shot.
